Athletic ball
First Claim
1. An athletic ball, comprising:
- (a) a ball having an airtight bladder for giving impact resilience to the ball in which compressed air is charged through an air injection valve,(b) a concave housing provided within the ball on the opposite portion of the ball from the valve and contacting the surface of the bladder while maintaining the airtightness of the bladder,(c) means for detecting an external force applied to the ball and generating a signal in response thereto,(d) operation means for converting the signal from the detecting means into a numerical information signal relating to the external force applied to the ball,(e) means for displaying the numerical information obtained in the operation means, and(f) a battery power source for driving the above means, said detecting means, operation means, displaying means and battery power source being accommodated in the housing, and the sum of the weight of the housing, the detecting means, the operation means, displaying means and battery power source being substantially the same as the weight of the valve, and said weight sum being small enough such that said housing and elements disposed therein do not substantially interfere with the impact resilience of the ball.

Abstract
An athletic ball comprising (a) a ball having an airtight bladder with an air injecting valve, (b) a housing provided with the ball on the opposite side of the valve without interfering the airtightness of the bladder, a detector for detecting an application of external force to the ball, an operation converter for converting the detected impact signal to a numerical information signal, a display for displaying the numerical information and/or for generating a sound according to the numerical information, and a battery power source; the converter, display and battery power source being accommodated in the housing, and the sum of the weights of all of the above elements being adjusted to the weight which does not substantially interfere the impact resilience of the bladder and is substantially the same as that of the valve.
